About this Add-on

Google Search and other search engines and websites seem to ignore Mozilla's 'Do-Not-Track'-header and add tracking functions to their search results and external links anyway.This add-on shows tracking-free links or optionally replaces the results with those links.

Multiprocess Firefox (Electrolysis, E10S), which can be enabled in Firefox 35 and higher, is not yet supported. If you want to continue to use this add-on, please disable E10S in your options for now. We're working on a solution.

Under Mac OS X, the preferences cannot be dismissed when started from the context menu or Firefox's privacy preferences. A workaround is described in this issue report. Using the preferences from the add-on manager should work properly.

Add-on compatibility

NoScript and Facebook: Facebook seems to detect an active NoScript and replaces external links with tracked ones. I do not have the intention to reverse this. Add Facebook to NoScripts trusted sites, if you want this add-on work.

One More ThingThis add-on does not -- and cannot -- recognize every mechanism companies use to track user behavior! In fact, this will be probably a losing battle.

With every redesign of a website, tracking mechanisms change, and this add-on will definitely become obsolete rather sooner than later. For our most used websites, We will try to keep this add-on as up-to-date as possible, but some others may fall through the cracks...

For this reason I suggest you don't use this add-on on its own. There are a lot of privacy and security add-ons out there, with RequestPolicy and FlashBlock being my favorites. I would recommend you to use these to together with this add-on. But there's also NoScript, which I personally don't use, but it comes highly recommended.

If you find that a website is starting to track you again or that this add-on is causing errors on a page, you can report the problem here.

If on the other hand, you want to help out and extend this add-on, see what developers can do!

Developer’s Comments

Google, YouTube, Yahoo!, Bing, Facebook and probably many other websites are trying to hide the fact that are tracking your clicks, even if you tell them not to.

They're doing this, sometimes by replacing the links as soon as press the mouse-button sometimes by adding other click handlers.

This means that even if you drag the seemingly harmless links to another tab or copy and paste the link, you still get tracked.

To see this effect (and for security reasons), I'd recommend you to install the excellent RequestPolicy add-on!

Development Channel

The Development Channel lets you test an experimental new version of this add-on before it's released to the general public. Once you install the development version, you will continue to get updates from this channel. To stop receiving development updates, reinstall the default version from the link above.

Caution: Development versions of this add-on have not been reviewed by Mozilla and can't be installed on release versions of Firefox.
